This emerald green lake, largest of all the glacial lakes in the Cordillera Blanca range lies in a valley with Huandoy (6395m) to the south and Aguja (5840m) to the north. There is no public transport to the area and I was lucky enough to have hitched a ride by a team of canoeists heading there. The almost perfect pyramidal shape mountain at the end of the lake is Pirámide de Garcilaso (5885m), with Chacraraju (6112m) sitting right next to it.
